Holy shit you guys. With some creative use of the vice grip and a lot of patience I got it open. Those screws where in there ridiculously tight. So tight it was bending in the back panel around the screw holes! I tried to take a guts shot but my sd card reader is apparently broken and I lost the cable that came with my camera. There are already better gut shots of ZR1000s out there than what my crappy camera phone will do.

Anyway - This guy had no idea what he was talking about. Its fucking flawless. There isn't even a finger print on the inside. Nothing is melted or burned. No bulging capacitors. Nothing loose or hanging. Nothing bent. It looks like it is brand new. The PCB is almost glowing. Even the serial sticker or whatever that is still has a bright white color and hasn't peeled at all. The worst thing I can say is there was a little bit of saw dust on the inside which I just blew out. As far as his speaker cable coming loose story goes It doesn't even look like that would do anything because the chassis doesn't touch anything metal. I think I just got a fully working ZR1000 for the price of a Walmart amp.

dang nice, as for the mosfet and transistor sometime you can't tell just like my old amp looks brand new took some of the transistor they stayed open no matter what but hook it up and see what it does

While I was playing around with my oscope and my other amp I did hook it up and it seems to power up and work fine. I don't have a clamp or anything so I can't measure watts but it got crazy loud so it seems to work fine! If it truly is putting out less than its supposed to its a very small amount. From what I recall it sounded about the same as my other one. I haven't had it in for awhile so its hard to say I really noticed any difference.

While you can't check watts, you could check output voltage. If the voltage on both amps is about the same, the wattage should be the same too I believe. Sounds like you might have caught a sweet deal lol.
